BELT-GUIDE.

SPECIFICATION formingpart of Letters Patent No. 648,615, dated Mayl, 1900.

Application filed July 18, 1898. Serial No. 686,302. (No model.)

To aZZ whom it may concern:

' Be it known that we, WILLIAM F. HAMIL- TON and JOHN HOMER DRAKE, citizens of the United States, residing at Ventura, in the county of Ventura and State of California, have invented new and useful Improvements in Belt-Guides, of which the following is a specification.

The object of our invention is to provide a simple device which can at all times and under all circumstances be relied upon to properly guide the power-driven'belt from the driving to the driven pulley and prevent the wind or any other disturbing element from in any manner interfering therewith and make the belt run true on the driven pulley, even when the driving-pulley is not true, and to cause the belt to run squarely on the center of the driven pulley under all conditions, and thereby lose no power by running to the side or off the pulley and slipping.

Our device is particularly adapted for use on threshing-machines, in the harvest-fields, or in any open situation where the drivingbelt is often exposed to strong and variable winds.

Ve accomplish these objects by the mechanism herein described, and shown in the accompanying drawings, in which- Figure 1 is a perspective view of our device, showing the belt in place on the same. Fig.

2 is a transverse sectional view taken on a.

line cutting both of the flanged guide-pulleys and the cross-piece to which they are at-' provided with an annular boss J, which rests on the upper side of the cross-piece H, and are held firmly against the same when the nuts K are screwed up tightly. In the cross piece II are longitudinal slots H, affording a longitudinal movement therein of the axles I, whereby the guide-pulleys may be readily adjusted to suit the width of the belt to be used. The drum E affords a rest for the belt and steadies the same-as it is drawn through the flanges on the guide-pulleys and over the drum. be thrown from the driven pulley, no matter how strong or variable the wind,and it will not slip on the pulley, causing thereby a loss of power.

Having described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. The herein-described adjustable beltguide, consisting of theframe A, having upright supports B, and cross-piece H, the crosspiece H being provided with longitudinal slots II in combination with the pulley'O, the drum E, the vertical flanged pulleys D, rotatively mounted on the axles I, the axles I, having bosses J, and being screw-threaded at both ends, the nuts K, and the belt F, substantially as shown and described.

2. In a belt-guide, two vertically-mounted rotatable pulleys, one on each side of the belt and having flanges adapted to extend, one above and the other below the edges of the belt, and means for their adjustment, in combination with a revoluble drum, horizon- A belt mounted in this way cannot tally mounted in line with the belt and im- WILLIAM F.
